JOHN HENRY STONE, or HAMILTON, ONTARIO, oANADA.

TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 392,626. that May a, 1888.

' Application filed April 17,1886. Serial No. 199,210. (No model.)

To 11% whom it may concern.-

Be it known that I, J oHN HENRY STONE, of the city of Hamilton, in the county of Wentworth, Province of Ontario, Dominion of Canada, manufacturer, have invented certain new and useful Improvements on Tubular Lan terns; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

My device relates to an improved removable reflector specially designed for tubular lanterns, but which may be used for other kinds; and it consists in a circular metal plate provided around its circumference with a frame cut to conform to the swell and shape of the globe at its largest diameter. It will contain a concave burnished plate, which may be tinned, silvered, nickel-plated, or otherwise, as required, and the reflector. maybe attached in any convenient manner to the lantern, say, by hooks to the guard, to the tubes,

or to the perforated globe-disk or top of the E is the spring-guard. F is the burner.

lantern.

By reference to the annexed drawings, forming part of this specification, it will be seen that Figure 1 represents a front elevation of my improved tubular lantern. Fig. 2 is a side elevation. Fig. 3 is a section showing one method of fastening the reflector.

AA are the tubes; B, the reservoir; 0, the perforated disk upon which the globe D rests. Gis the reflector, consisting of the back a, the flange b surrounding the back a and out closely to fit the rotundityof the globe D, to prevent mud, dust, or any deleterious material getting I in between the globe and reflector to tarnish its. smooth and polished surface.

0 is the concave burnished plate secured to the back a. The reflector will be so placed that its center will be about opposite the flame of the burner, so as to focus the light, and capable of throwing the light a long distance forward and at a 'considerable angle at each side, similar to a locomotive head-light. It may be observed that the said reflectorconstructed and placed as shown may beheld in its place in any convenient manner-such as by hooks d soldered to the flange b and made to catch on the guard E, by which it is easily adjusted to the lantern or removed; or where the guard is not used wires 6 maybe attached to the reflector, one on each side, and made to pass over to the tubes, have their ends bent down, and inserted in corre sponding sockets f, soldered to the tubes A;

or the said reflector may be attached to the perforated globe-disk O. or to the top part of thelantern. In any case it must be made to be removable, so as to be easily taken off when the light is wished to be diffused equally on all sides. 7

Having thus described'my device and its advantages, what I claim as my invention, and desire to secure by Letters Patent, is- I 1. The combination, with a tubular lantern, of a removable reflector, G, having its flange b cut to conform to and fit the shape of the globe, substantially as specified. A

2. The combination,with a tubular 13.11%".

of a reflector, G, having its flange bout to form to and fit the round shape of the globe, V

and secured to the guard E by hooks d,- substantiallyas specified.

Dated at Hamilton, Ontario, Canada, this 23d day of March, A. D. 1886.
